Geographically Diverse Fiber for<br />

Redundant WAN Connectivity<br />

<strong>CIT</strong> maintains a fiber p<strong>at</strong>hway for<br />

d<strong>at</strong>a along the east side of Cayuga Lake<br />

to Syracuse . This year an additional<br />

fiber p<strong>at</strong>h was built up the west side<br />

of the lake to Rochester . The new fiber<br />

p<strong>at</strong>h meets a number of important<br />

needs for the campus, increasing<br />

communic<strong>at</strong>ion capabilities, security<br />

options, <strong>and</strong> connectivity backups .<br />

A spur off the main fiber <strong>at</strong>taches<br />

to the Geneva Research St<strong>at</strong>ion,<br />

providing ten gigabit-per-second d<strong>at</strong>a<br />

connectivity <strong>and</strong> better phone service<br />

to the Geneva campus . This allows<br />

videoconferencing between Geneva<br />

<strong>and</strong> Ithaca <strong>and</strong> also gives researchers<br />

in Geneva access to the Center for<br />

Advanced <strong>Computing</strong> <strong>and</strong> large<br />

d<strong>at</strong>abases on the Ithaca campus . In the<br />

event of a disaster, the Geneva facilities<br />

can now be leveraged as an emergency<br />

staging area for Ithaca comput<strong>at</strong>ional<br />

resources .<br />

At Rochester, there is a backup<br />

Internet2 Research <strong>and</strong> Educ<strong>at</strong>ion<br />

connection th<strong>at</strong> is autom<strong>at</strong>ically<br />

brought up if there is a loss of <strong>Cornell</strong>’s<br />

main Internet2 connection . Internet2<br />

is a high-speed network for higher<br />

educ<strong>at</strong>ion . The Rochester connection<br />

also allows <strong>Cornell</strong> to dynamically form<br />

a ring back to <strong>Cornell</strong>’s equipment<br />

in Syracuse in case of a break in the<br />

fiber connection between Ithaca <strong>and</strong><br />

Syracuse to re-establish our multiple<br />

connections to NYC .<br />

Network Capacity Doubled for<br />

EZ-Backup <strong>and</strong> Other Initi<strong>at</strong>ives<br />

<strong>CIT</strong> lit up an additional 10 gigabitper-second<br />

connection from Ithaca<br />

to Syracuse to New York City . From<br />

the <strong>Cornell</strong> router <strong>at</strong> 32 Avenue of<br />

Americas, it provides high-speed<br />

connectivity to Weill <strong>Cornell</strong> Medical<br />

College, as well as to many other<br />

research institutions around the world .<br />

The 10 Gbps lambda is not a<br />

physical connection, but a particular<br />

wavelength of light used across a<br />

series of Dense Wavelength Division<br />

Multiplexing (DWDM) connections .<br />

EZ-Backup d<strong>at</strong>a is sent across the<br />

connection to a secure secondary<br />

system <strong>at</strong> the Weill <strong>Cornell</strong> Medical<br />

College facility . The connection can<br />

also be used for real-time video<br />

collabor<strong>at</strong>ion between the two<br />

campuses .<br />

Comprehensive Video Streaming<br />

Architecture Emerges as a<br />

Campus-Wide Need<br />

In 2009, <strong>CIT</strong> launched a campus-wide<br />

collabor<strong>at</strong>ive effort to develop video<br />

streaming technology st<strong>and</strong>ards <strong>and</strong><br />

support services for the future .<br />

While the university has been<br />

streaming video for years, the<br />

continuing increase in dem<strong>and</strong><br />

underscores the necessity for a scalable<br />

architecture th<strong>at</strong> accommod<strong>at</strong>es the<br />

variety of video streaming needs across<br />

campus—everything from podcast<br />

quality to the near-broadcast quality<br />

usually needed for distance learning<br />

classes .<br />

The new architecture will define:<br />

▪ A content management system for<br />

c<strong>at</strong>aloging, editing, <strong>and</strong> publishing<br />

audio/video streams .<br />

▪ An audio-video capture system for<br />

producing a range of quality, <strong>and</strong><br />

servicing a variety of venues . For<br />

example, <strong>Cornell</strong> might need some<br />

systems th<strong>at</strong> are fixed in one place,<br />

perhaps in selected classrooms,<br />

<strong>and</strong> some portable systems th<strong>at</strong> are<br />

easily moved .<br />

▪ A media hosting solution for<br />

storing video <strong>and</strong> serving it out in<br />

appropri<strong>at</strong>e form<strong>at</strong>s .<br />

The first step in the process has been<br />

to engage the university community<br />

in a series of discussions held during<br />

the 2009 IT Forum <strong>and</strong> two video<br />

summits hosted by <strong>CIT</strong> <strong>and</strong> <strong>at</strong>tended by<br />

members of <strong>Cornell</strong>‘s Ithaca <strong>and</strong> Weill<br />

<strong>Cornell</strong> Medical College audio-visual<br />

communities .<br />

A variety of needs, concerns,<br />

questions, <strong>and</strong> approaches emerged<br />

along with a straw architecture based<br />

on st<strong>and</strong>ard technologies <strong>and</strong> systems .<br />

The next step is to establish a video<br />

streaming task force to advise <strong>CIT</strong> <strong>and</strong><br />

<strong>Cornell</strong> as the university develops its<br />

comprehensive video streaming plan .
